CHAPTER 7: Reinforced Concrete Column and Wall

Footings 7.3 Pile Cap ConfigurationsSSA

Description

This application calculates pile coordinates and pile cap plan dimensions for pile groups with 2 to 20 piles.The purpose of this application is to show the pile group layout, pile coordinates and plan dimensions used inSection 7.2 for selecting pile cap depth and reinforcement.

The user must enter the minimum pile spacing, factors for rounding pile coordinates and pile cap plandimensions to practical dimensions, and the minimum edge distance from center of pile to outside face ofconcrete.

Input

Input Variables

Minimum pile spacing: s≔3⋅

1 Factor for rounding pile spacing: SzP ≔ ―⋅ 2

Factor for rounding pile cap dimensions: SzD ≔ 1 ⋅

Minimum edge distance from center of pile: E≔1⋅ +3⋅

Computed Variables

X the longer plan dimension of the pile cap

Y the shorter plan dimension of pile cap x pile coordinates in the X direction from the centroid of the pile group y pile coordinates in the Y direction from the centroid of the pile group
